Troubleshooting Common WordPress Errors and How to Fix Them

WordPress / By

WordPress is one of the most popular content management systems in the world, but like any platform, it can sometimes run into issues. Whether you’re a beginner or an experienced user, encountering errors on your WordPress site is inevitable at some point. Fortunately, most WordPress errors can be resolved quickly with the right troubleshooting steps.

In this article, we’ll cover some of the most common WordPress errors and provide simple solutions to help you get your site back up and running smoothly.

1. White Screen of Death (WSOD)

The White Screen of Death is one of the most frustrating WordPress errors. When this happens, your website displays a blank screen, making it impossible to access your content.

How to Fix:

  • Deactivate all plugins: Sometimes, a malfunctioning plugin causes this error. You can deactivate all plugins by accessing your site via FTP or your hosting provider’s file manager and renaming the plugin folder.
  • Switch to a default theme: Your active theme might be causing issues. Go to your wp-content/themes folder and temporarily switch to a default WordPress theme (like Twenty Twenty-One).
  • Increase memory limit: A lack of memory could cause the WSOD. You can increase your PHP memory limit by adding the following line to your wp-config.php file: define('WP_MEMORY_LIMIT', '256M');

2. 404 Page Not Found Error

If visitors can’t access certain pages on your site and are greeted with a 404 error, it means WordPress can’t find the page.

How to Fix:

  • Update Permalinks: Go to Settings > Permalinks in your WordPress dashboard. Simply click Save Changes to refresh your permalinks structure. This often resolves the issue.
  • Check the .htaccess file: If updating permalinks doesn’t work, check the .htaccess file in your root directory. You can regenerate it by going to Settings > Permalinks and clicking Save Changes again.

3. Error Establishing a Database Connection

This error occurs when WordPress can’t connect to your database, which is essential for loading your site’s content.

How to Fix:

  • Check your wp-config.php file: The most common cause of this issue is incorrect database credentials. Make sure your database name, username, and password in the wp-config.php file are correct.
  • Test your database connection: If you have access to your hosting control panel (e.g., cPanel), try to connect to the database via phpMyAdmin to check if the database is working properly.
  • Repair the database: Sometimes, the database itself may be corrupted. You can add the following line to your wp-config.php file to enable the database repair feature: define('WP_ALLOW_REPAIR', true); Then, visit http://yoursite.com/wp-admin/maint/repair.php to repair the database.

4. Internal Server Error (500 Error)

The 500 Internal Server Error is a generic error message that doesn’t tell you exactly what’s wrong, but it typically happens due to a problem with the server configuration or WordPress settings.

How to Fix:

  • Deactivate plugins: A faulty plugin could be causing this error. Deactivate all plugins by renaming the plugins folder and check if the error is resolved.
  • Check the .htaccess file: Corrupt .htaccess files can cause 500 errors. Rename your .htaccess file to .htaccess_old and then go to Settings > Permalinks and click Save Changes to regenerate the .htaccess file.
  • Increase PHP limits: Sometimes, the server limits may cause the error. You can increase the PHP memory limit by adding this line to wp-config.php: define('WP_MEMORY_LIMIT', '256M');

5. Connection Timed Out Error

The Connection Timed Out error typically happens when your server is overwhelmed and can’t complete a request. This could be due to issues with your hosting or a resource-heavy plugin.

How to Fix:

  • Deactivate plugins and themes: Disable all plugins and switch to a default theme to check if a plugin or theme is causing the issue.
  • Increase PHP limits: The error may occur if your site is trying to load too many resources at once. Increase your PHP memory and execution time limits by adding the following code to wp-config.php: define('WP_MEMORY_LIMIT', '256M'); set_time_limit(300);

6. Too Many Redirects Error

A redirect loop happens when a page keeps redirecting to itself or another page in a never-ending loop. This is commonly caused by incorrect settings or conflicting plugins.

How to Fix:

  • Clear browser cookies: Start by clearing your browser’s cookies and cache, as these may be causing the loop.
  • Check WordPress URL settings: Go to Settings > General in your dashboard. Make sure your WordPress Address (URL) and Site Address (URL) are correct and don’t include “www” or “https” unless necessary.
  • Disable caching plugins: If you’re using caching plugins, disable them to ensure they aren’t causing the redirect loop.

7. White Text and Missing Visual Editor (TinyMCE)

Sometimes, WordPress posts may show only white text, and the visual editor may stop working, preventing you from creating or editing content easily.

How to Fix:

  • Clear browser cache: Try clearing your browser’s cache or testing in an incognito window to see if the issue persists.
  • Deactivate plugins: Some plugins, particularly caching or security plugins, can cause the editor to stop working. Deactivate plugins one by one to identify the culprit.
  • Check for JavaScript errors: JavaScript errors can prevent the editor from loading. You can check for errors by opening the browser’s developer tools and viewing the console.

8. Fatal Error: Allowed Memory Size Exhausted

When you see the message “Fatal error: Allowed memory size of xxx bytes exhausted”, it means your site is using more PHP memory than your hosting server allows.

How to Fix:

  • Increase PHP memory limit: Add the following line to your wp-config.php file to increase the memory limit: define('WP_MEMORY_LIMIT', '256M');
  • Deactivate plugins and themes: A resource-heavy plugin or theme could be consuming too much memory. Try disabling all plugins and switching to a default theme.
